OIL-'GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 778,577, dated December 2'7, 1904.

Application filed January 26, 1903. Serial No. 140,648.

To (117/ who??? it may concern.-

Be it known that 1. JOHN LESLIE HAGUE, a citizen of the United States, residing at Los Angeles, in the county of Los Angcles and 5 State of California, have invented a certain Improved Oil-Gas Burner, of which the following is a specification.

This invention relates to burners adapted for burning heavy hydrocarbons; and its gen- IO eral object is to provide a simple, cheap, and

efficient device whereby heavy crude asphaltum oils may be vaporized and the vapor burned and the heavy residuum drained from the burner.

A further object is to provide in such a burner a vaporizing-chamber comprising a primary chamber into which the crude oil is introduced and a secondary or superheating chamber to which the volatilized portion of the oil conducted from the heavy involatile portions and from which the vapor is conducted to be burned, and to provide means for withdrawing or draining the heavy involatile and residuum portions from the primary chamber.

Other and further objects and ends in view will hereinafter appear from the detail description of construction and operation.

The invention consists, in general, in ahori- Zontal vaporizing-chamber comprising a .pri-

mary volatilizingchamber into which the crude or heavy oil is introduced and a secondary or superheating chamber leading from the upper portion of said primary chamber and through which the volatilizable portions of the oil pass and are superheated as they pass therethrough to the burner-jet.

The invention consists, further, in providingmeans for draining theinvolatile portions from said primary chamber and in means for directing the burning vapor against said vaporizing-chamber and in means for suitably spreading the flame to thoroughly heat said chamber.

The invention consists, further, in the constructions hereinafter described, and particularly pointed out in the claims, and will be more readily understood by reference to the accompanying drawings, forming part of this specification, in which Figure I is a fragmental perspective view of a stove equipped with an oil-gas burner embodying my invention. Fig. II is a longitudinal sectional view of an oil-gas burner embodying my invention, the same being shown detached from the stove.

As shown in the drawings, A represents a stove or range, a portion of the top plate and fire-pot being broken away to show the burner in position.

2 represents a horizontal pipe or tube having a lateral inlet-duct 3, connected with a suitable supply-pipe 4. A valve 5 is preferably interposed in this pipe to regulate the supply of oil to the burner. The tube or pipe 2 is formed in two portions of varying diameters, the forward or volatilizing chamber 6 communicating directly with the superheatingchamber 7 from the upper portion of said volatiliZing-chamber, so that a receptacle is formed into which the heavy involatile portion of the oil 'is deposited, from Which the residuum or heavy involatile portions may be drained through an outlet 8, a drain-pipe 9 being connected thereto and a valve 10 interposed in said pipe to control the drain from the chamber 6.

The end of the pipe 2 is closed by a removable plug 11, by removing which access can be had to the chamber 6 to clean the same, if neces- I sary. Moreover, the chamber 7 being in line with the removable plug 11 access can also be had to said chamber 7 to clean same when said plug is removed. A pipe 12 is connected to the other end of the pipe or tube 2 by a nipple 13 and union or elbow-coupling l4, and this pipe is in turn connected with the pipe 15, by

a union or elbow-coupling 16. The end of the pipe 15 is closed by'a cap 17.

18 represents the vapor discharge or outlet from the pipe 15, which, asshown, is preferably parallel With the tube or pipe 2, but may be adjusted by revolution in the union 16 or by revolution of the union 1 k.

19 represents a spreader provided on the tube or pipe 2, and against which the burning vapor from the outlet 19 is adapted to strike, being thereby directed to all sides. This spreader is preferably provided with a loop 20, adapted to slip on the pipe 2, and a flat flange 21, forming the spreading portion. The spreader is thus adjustably mounted on the pipe or tube 2 and may be turned to direct the flame as desired.

In order that the plug 11 may not be seriously affected by the heat of the fire, it is desirable that it should be outside the fire-box, and to further protect this joint it is desirable that the outer member of the joint should be heavy or thick. I attain both these ends and at the same time provide a convenient support for the whole burner by making the larger or volatilizing-chamber endof the tube 2 with a heavy flange 22, which is fastened to the wall 23 of the lire-box in any suitable manner, as by bolts 24, so that the outer end of this chamber is exposed on the outside of the lire-box when theplug is removed, and said plug and its screw-joint are outside of the fire-box. l have found that when a plug of this character located within the the box or lire-pot it is liable either to be oxidized tightly into place, so that it cannot be removed, or to become so loose on account of the greater expansion of the outer member of the joint that gas will escape at the joint. The described construction also enables the entire burner device to be supported from the wall of the fire-box by flange 22. In practice the residue accumulating at the bottom of chamber 6 is so heavy or thick that it will not flow except when warmed, and it is important that the drainage-outlet should be capable of being opened when the device is hot and a pressure exists in the retort acting to expel the residue. I therefore extend the operating-handle 25 of the drain-valve 10 through the wall of the fire-box so to be accessible from the outside while the burner is in operation. By supporting the superheater and burner tubes on the vaporizing-chamber, which in turn is supported by flange-support 22, 1 am enabled to more readily maintain the superheater and burner at the high temperature required, the device being attached to the stove by the portion thereof that is naturally lowest in temperature.

The flame from the jet 18 beats the fire-pot and projecting against the tube or pipe 2 heats the same. As the heavy oil enters the chamber 6 the volatilized portion rises and passes through the chamber 7 to the outlet. The heavy involatile portions are precipitated to the bottom of chamber 6, from whence they may be drawn off through the drain-pipe 9. By thus constructing the vaporizingchamber in two sections any precipitation from the oil is prevented from passing into the chamber 7 or pipes 12 and 15. Any carbonization will take place in chamber 7 and can be readily cleaned out by removing the plug 11.

It will be noted that the jet from the opening 18 impinges directly upon the spreader 19 and the greatest heat is applied to the superheating-chambei- 7. A portion of the reflected heat from the spreader or deflector 19 strikes walls of the chamber 6, thus applying thereto a modified heat which will not cause such precipitate vaporization as to cause carbonization in the chamber 6, which would ocour in a vexatious degree were the jet to impin go directly upon the walls of the chamber 6.

Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. An oil-gas burner comprising a horizontal tube, said tube having two portions of different diameters, the portion of larger diameter forming the volatilizingchamber and provided with an inlet, and the portion of smaller diameter forming a superheatingchamber, said superheating-chamber communicating with said volatilizing-chamber above the center thereof, and a discharge-pipe connected with said superheating-chamber and provided with an outlet adapted to impinge its stream against the walls of said chamber, said vaporizing-chamber being provided with a drainoutlet, and means in connection therewith for controlling the passage of involatile portions therethrough.
